The intricate world of asymmetric synthesis relies on specialized chemical tools, and chiral phosphine ligands are among the most important. (S)-(-)-2,2'-Bis[di(3,5-xylyl)phosphino]-1,1'-binaphthyl, identified by CAS number 135139-00-3 and commonly known as (S)-Xylyl-BINAP, is a prominent example. This ligand, characterized by its C52H48P2 molecular formula and a molecular weight of 734.89, is a white to pale yellow crystalline solid prized for its excellent catalytic properties in creating enantiomerically pure compounds.

Its applications span critical areas such as pharmaceutical intermediate synthesis and the development of advanced electronic materials like those used in OLEDs. The efficacy of (S)-Xylyl-BINAP stems from its ability to impart high enantioselectivity in reactions like asymmetric hydrogenation, metal-catalyzed cycloadditions, and asymmetric fluorination. Understanding these applications is key for R&D scientists seeking to optimize their synthetic pathways.
